dc.description.abstract	Synergistic effects of 3D printing and composites expand the opportunities for designing high-performance light weight structures like auxetic lattices, that exhibit negative Poisson’s ratio. This thesis endeavors design, simulation, and experimental verification of 3D printed auxetic structures with an aim to attain improved energy absorption and young’s modulus by suggesting intuitive designs such as introducing low rotational stiffness nodes, vertical struts, and tessellation (arrangement of basic building block in the design space) followed by characterization of compressive behaviour of cementitious composites embedded with 3D printed re-entrant structure.
